Cassini watches storm choke on its own tail

(Phys.org)—Call it a Saturnian version of the Ouroboros, the mythical serpent that bites its own tail. In a new paper that provides the most detail yet about the life and death of a monstrous thunder-and-lightning storm ...

A microquasar makes a giant Manatee Nebula

(Phys.org)—A new view of a 20,000-year old supernova remnant demonstrates the upgraded imaging power of the National Science Foundation's (NSF) Karl G. Jansky Very Large Array (VLA) and provides more clues to the history ...

Shot away from its companion, giant star makes waves

(Phys.org)—Like a ship plowing through still waters, the giant star Zeta Ophiuchi is speeding through space, making waves in the dust ahead. NASA's Spitzer Space Telescope has captured a dramatic, infrared portrait of these ...

Seeking the deadly roots of the dinosaurs' ascent

Over the past 450 million years, life on earth has undergone at least five great extinctions, when biological activity nosedived and dominant groups of creatures disappeared. The final one (so far) was 65 million years ago, ...

Fukushima was 'man-made' disaster: Japanese probe

Last year's nuclear accident at Fukushima was a man-made catastrophe and not only due to the tsunami that hit the plant, a Japanese parliamentary panel said Thursday in its final report on the disaster.

ALMA turns its eyes to Centaurus A

(Phys.org) -- A new image of the galaxy Centaurus A, made with the Atacama Large Millimeter/submillimeter Array (ALMA), shows how the observatory allows astronomers to see through the opaque dust lanes that obscure the galaxy's ...

Record-breaking radio waves discovered from ultra-cool star

Penn State University astronomers using the world's largest radio telescope, at Arecibo, Puerto Rico, have discovered flaring radio emission from an ultra-cool star, not much warmer than the planet Jupiter, shattering the ...

Astronomers detect coolest radio star

(Phys.org) -- Astronomers using the world's largest radio telescope, at Arecibo, Puerto Rico, have discovered flaring radio emission from an ultra-cool star, not much warmer than the planet Jupiter, shattering the previous ...

Under pressure: Ramp-compression smashes record

In the first university-based planetary science experiment at the National Ignition Facility (NIF), researchers have gradually compressed a diamond sample to a record pressure of 50 megabars (50 million times Earth's atmospheric ...
